Incidentally in the past ten years I picked up an Apple component video out connector. I think it might have been designed for an iBook! Turns out it works with my old iPod, but only if I swap the RCA video and sound connectors (the color codes are wrong). Diliger tells us that camcorder manufacturers gave us the pin order variation:

Apple's iPod headphone jacks had to remain compatible with standard headphones, so Apple reversed the odd pin order used by camcorder makers to deliver a headphone jack that worked fine with regular headphones, but could also deliver video output when used with the iPod AV Cable. Camcorder cables could be used by simply reversing the order that the RCA connector ends are plugged into on the TV side.
